Bug description:
  mir_demo_server crashes with:

     ERROR: Dynamic exception type: std::out_of_range
     std::exception::what: map::at

  when an Xmir rootless app is closed by its File menu.

  This does not happen in mir_demo_server_minimal or mir_proving_server.
  It might have something to do with child/parent surface relationships
  and the fact that closing an app (like gedit) involves having a menu
  open (which to Mir at least is a child of the app window).
